Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The arc rods 67 are rotatably installed on the top of the base 66, the square block 69 is fixedly installed on the surface of the load-bearing plate 63, the transmission rod 610 is rotatably installed on the end of the square block 69 away from the load-bearing plate 63, and the blocking plate 611 is fixedly installed on the top of the square block 69, so that the arc rod 67 supports the pipe body when moving, and does not continue to move after moving to the desired position, ensuring that the position of the pipe body for detection will not be offset, thereby improving the accuracy of the detection.

[0021] A No. 1 spring 68 is provided between the base 66 and the arc rod 67 , and the transmission rod 610 is in contact with the blocking plate 611 , and the arc rod 67 is driven to reset by the No. 1 spring 68 .

[0022] A method for using a bellows lateral force detection device comprises the following steps: Step 1: Place one end of the tube body inside the housing 2. When the tube body is too heavy, the tube body moves toward the bottom, which drives the base 66 to move toward the bottom. The base 66 moves toward the bottom, which drives the load-bearing plate 63 to move toward the bottom. The load-bearing plate 63 moves toward the bottom, which drives the output end of the elastic telescopic rod 62 to move toward the bottom. Step 2: The elastic retractable rod 62 drives the load-bearing plate 63 to move toward the top through its own elastic reset, and the driving device 61 drives the connecting seat 64 to move toward the inside of the housing 2, and the movement of the connecting seat 64 drives the connecting rod 65 to move toward the inside of the housing 2; Step 3: The connecting rod 65 moves to drive the connecting seat 64 at the other end to move, the movement of the connecting seat 64 drives the load-bearing plate 63 to move, the movement of the load-bearing plate 63 drives the base 66 to move, and the movement of the base 66 drives the tube body to move toward the inside of the housing 2; Step 4: When measuring a threaded pipe that is too heavy or too long, the pipe body can also be placed to facilitate the operation of the staff and improve the convenience of using the device.

[0023] When the present embodiment is working, one end of the tube body is placed inside the shell 2. When the tube body is too heavy, the tube body moves toward the bottom, which drives the base 66 to move toward the bottom. The base 66 moves toward the bottom, which drives the load-bearing plate 63 to move toward the bottom. The load-bearing plate 63 moves toward the bottom, which drives the output end of the elastic telescopic rod 62 to move toward the bottom. The elastic resetting of the elastic telescopic rod 62 drives the load-bearing plate 63 to move toward the top. The driving device 61 drives the connecting seat 64 to move toward the inside of the shell 2. The movement of the connecting seat 64 drives the connecting rod 65 to move toward the inside of the shell 2. The movement of the connecting rod 65 drives the connecting seat 64 at the other end to move. The movement of the connecting seat 64 drives the load-bearing plate 63 to move. The movement of the load-bearing plate 63 drives the base 66 to move. The movement of the base 66 drives the tube body toward the inside of the shell 2. The device can be moved so that when measuring a threaded pipe that is too heavy or too long, the pipe body can also be placed, which is convenient for the staff to operate and improves the convenience of the device when used. The movement of the pipe body toward the bottom will drive the arc rod 67 to rotate toward the bottom, and the arc rod 67 will rotate toward the top through the reset of the No. 1 spring 68. The movement of the load-bearing plate 63 will drive the square block 69 to move toward the inside of the shell 2. The movement of the square block 69 will drive the transmission rod 610 to move toward the inside of the shell 2. The movement of the transmission rod 610 will contact the inner wall of the shell 2. After the transmission rod 610 is blocked by the shell 2, it cannot move further, so that the arc rod 67 supports the pipe body when moving, and does not move further after moving to the desired position, ensuring that the position of the pipe body for detection will not be offset, thereby improving the accuracy of the detection.

[0024] See also Figure 1-Figure 9On the basis of the above embodiment, in another embodiment of the present invention, a clamping device and a stabilizing device are arranged on the top of the bottom plate 1, wherein the clamping device comprises: a servo motor 71, a circular plate 72, a disc 73, an inner support block 74 and a round rod 75, the servo motor 71 is fixedly mounted on the surface of the housing 2, the output end of the servo motor 71 rotates and penetrates the inner and outer walls of the housing 2, the circular plate 72 is fixedly mounted on the top of the bottom plate 1, a square groove is opened on the surface of the circular plate 72, the disc 73 is fixedly mounted on the circumferential surface of the output end of the servo motor 71, and the disc An arc groove is provided on the surface of 73, and an inner support block 74 is slidably installed on a side of the circular plate 72 away from the servo motor 71. A round rod 75 is slidably installed on the inner wall of the arc groove. One end of the round rod 75 close to the disc 73 is connected to the inner support block 74, so that the tube body can be clamped from the inside by controlling the forward and reverse rotation of the output end of the servo motor 71. The tube body can be limited without squeezing the tube body from the outside and without changing the external shape of the tube body, thereby preventing the position of the tube body from shifting during detection, thereby further improving the accuracy of detection.

[0025] The clamping device also includes: a cross bar 76, two clamping plates 77 and a transmission arc rod 78. The cross bar 76 is fixedly installed on the surface of the inner support block 74, and the two clamping plates 77 are fixedly installed between the circular plate 72 and the outer shell 2. The transmission arc rod 78 is rotatably installed between the clamping plates 77, so that when the feeding device fails to transport the threaded pipe to the required area, the servo motor 71 cannot be started to clamp the pipe body, thereby preventing the pipe body from failing to reach the required area and resulting in the inability to effectively clamp the pipe body, thereby improving the reliability of the detection result.

[0026] A torsion spring No. 1 is arranged between the transmission arc rod 78 and the clamping plate 77. The transmission arc rod 78 contacts the transmission rod 610, and the transmission arc rod 78 is driven to reset by the torsion spring No. 1.

[0027] The stabilizing device includes: a fixed arc rod 81, a U-shaped rod 82, a transmission long rod 83, a triangular block 84, a rotating arc rod 85, a connecting rotating rod 86 and two square plates 87. The fixed arc rod 81 is fixedly installed at the bottom of the top cover 3, the U-shaped rod 82 is fixedly installed at the bottom of the top cover 3, the transmission long rod 83 is slidably installed on the inner wall of the U-shaped rod 82, the triangular block 84 is fixedly installed on the top of the cross bar 76, the rotating arc rod 85 is rotatably installed on the surface of the fixed arc rod 81, one end of the connecting rotating rod 86 is rotatably installed on the end of the rotating arc rod 85 away from the fixed arc rod 81, and the connecting rotating rod 86 is rotatably installed on the end of the rotating arc rod 85 away from the fixed arc rod 81. The other end of the rod 86 is rotatably mounted on the end of the transmission long rod 83 close to the fixed arc rod 81 to prevent the tube from rupturing due to the pressure on the tube being greater than the maximum pressure that the tube can withstand during detection. The residual stress generated by the rupture of the tube will act on the detection end of the detector 5, causing deviation in the detection data, further improving the reliability of the measurement results of the device. The two square plates 87 are fixedly mounted at both ends of the transmission long rod 83. A transmission groove is provided on the surface of the transmission long rod 83 to prevent damage caused by mutual friction between the devices and improve the service life of the devices.

[0028] A No. 2 spring 88 is provided between the square plate 87 and the housing 2 , and the rotating arc rod 85 contacts the output end of the hydraulic rod 4 , and the No. 2 spring 88 drives the square plate 87 to reset.

[0029] A second torsion spring is provided between the connecting rotating rod 86 and the transmission long rod 83, and the triangular block 84 is in contact with the transmission groove, and the connecting rotating rod 86 is driven to reset by the second torsion spring.

[0030] When the present embodiment is working: the servo motor 71 is started, the rotation of the output end of the servo motor 71 drives the disc 73 to rotate, the rotation of the disc 73 drives the arc groove to rotate, the rotation of the arc groove drives the round rod 75 to move on the inner wall of the arc groove, the movement of the round rod 75 drives the inner support block 74 to move away from the output end of the servo motor 71, and the movement of the inner support block 74 supports the tube body from the inside. When the output end of the servo motor 71 is reversed, the rotation of the output end of the servo motor 71 drives the disc 73 to rotate, the rotation of the disc 73 drives the arc groove to rotate, the rotation of the arc groove drives the round rod 75 to move on the inner wall of the arc groove, and the movement of the round rod 75 drives the inner support block 74 to move toward the output end of the servo motor 71, so that the tube body can be clamped from the inside by controlling the forward and reverse rotation of the output end of the servo motor 71. By not squeezing the tube body from the outside, the tube body can be limited without changing its external shape, thereby preventing the tube body from shifting during detection, further improving the accuracy of detection. The transmission rod 610 moves and contacts the transmission arc rod 78. The blocking plate 611 prevents the transmission rod 610 from rotating toward the bottom. The movement of the transmission rod 610 drives the transmission arc rod 78 to rotate in the direction of the servo motor 71. After the rotation of the transmission arc rod 78, it no longer blocks the inner support block 74, so that the inner support block 74 can move in a direction away from the output end of the servo motor 71, so that when the feeding device fails to transport the threaded tube to the required area, the servo motor 71 cannot be started to clamp the tube body, thereby preventing the tube body from failing to reach the required area and resulting in the inability to effectively clamp the tube body, thereby improving the reliability of the detection result.

[0031] The movement of the inner support block 74 will drive the cross bar 76 to move toward the top, and the movement of the cross bar 76 will drive the triangular block 84 to move toward the top. The movement of the triangular block 84 toward the top will contact the transmission groove, and the movement of the triangular block 84 will drive the transmission long rod 83 to move away from the hydraulic rod 4. The movement of the transmission long rod 83 will drive the connecting rotating rod 86 to rotate, and the rotation of the connecting rotating rod 86 will drive the rotating arc rod 85 to rotate. After the rotating arc rod 85 rotates, it fixes the output end of the hydraulic rod 4 through the cooperation with the fixed arc rod 81 to prevent the residual stress generated by the rupture of the tube body from acting on the detection end of the detector 5 when the pressure on the tube body is greater than the maximum pressure that the tube body can withstand during the detection, resulting in the detection data being biased. The difference further improves the reliability of the measurement results of the device. The movement of the cross bar 76 toward the bottom will drive the triangular block 84 to move toward the bottom. After the triangular block 84 moves, it will no longer contact the transmission groove. The No. 2 spring 88 is reset to drive the square plate 87 to move away from the hydraulic rod 4. The movement of the square plate 87 will drive the transmission long rod 83 to move away from the hydraulic rod 4. The movement of the transmission long rod 83 will drive the connecting rotating rod 86 to rotate. The rotation of the connecting rotating rod 86 will drive the rotating arc rod 85 to rotate. After the rotating arc rod 85 rotates, it will no longer contact the output end of the hydraulic rod 4, so that when the detection is completed or not performed, the rotating arc rod 85 will not contact the output end of the hydraulic rod 4, thereby preventing the devices from being damaged due to mutual friction and improving the service life of the device.
